THE first ever coal quality results from the Kokkia area of Celsius Coal’s Uzgen Basin Coking Coal Project further improve the overall coking properties of the project. The raw coal laboratory tests confirm good coking properties in all four holes tested.
Celsius Coal’s prospects in the Kyrgyz Republic of Central Asia.
Most sample results show Free Swell Index (FSI) numbers in the range of 7.5 to 9.5, indicating good coking potential. Sixty of the 63 samples analysed from the drill holes show FSI levels greater than 4.5, which is typically assessed as a threshold for coking coal.
Compared to the neighbouring Kargasha area, Kokkia’s FSIs are on average 1.0 to 1.5 points higher. Sulphur content appears slightly higher than Kargasha but previous Kargasha float/sink testing suggests sulphur levels can be reduced by coal washing.
Commenting on the test results, Celsius’ executive chairman Alex Molyneux says, “Recognizing the potential of the Kokkia area for coking coal we decided to do a significant amount of work there in the 2013 exploration season. The test results confirm our contention that the coking properties are even better on that side of the deposit so the work we did has certainly improved the quality of our Uzgen Basin Coking Coal Project. Integration of this work into our ongoing mining studies is under way, and the results are being communicated to potential off-take partners.”
The Kokkia results followed those from the Kargasha area. The tests were undertaken by the internationally accredited SGS laboratory in Novokuznetsk, Russia, using industry standard procedures. Results were also used to validate thickness of coal intersected in drilling from prior visual inspection.
Coking coal potential is demonstrated by the FSI results with 46 of 49 coal samples from four drill holes at Kargasha returning results greater than 4.5.
All coal samples also show very good thermal characteristics with high GCV (air dried gross calorific value, very low inherent moisture and acceptable total sulphur. Coking coals with low concentrations of deleterious elements such as phosphorus and total sulphur are preferred by steel producers.
Results holes are consistent with the 2012 laboratory results and continue to show a consistently high FSI and a low to moderate total sulphur trend. Given the spacing of the drill holes it suggests that most of the Kargasha area has coking coal potential.
Samples from two PQ drill holes have been received at ALS Richlands laboratory in Australia and work has started on Coke Strength after Reaction (CSR) analysis. The company expects to receive the results from the ongoing test work in the balance of the March quarter. Results will assist Celsius with its mining studies that are under way and in discussions with potential offtake partners.
